I don't know if the Catholic Church is breathing its last breath, but IMO it should be. Not even necessarily because so many of its priests are pedophiles, but because its doctrines are firmly embedded in what was logical 2000 years ago. Society has progressed, but the ideals of the Catholic Church (no birth control, no women in the priesthood) really haven't, and they simply aren't practical anymore. Either they need to realize this and adapt accordingly, or face extinction as concepts that made sense centuries ago become increasingly less easy to reconcile with modern society.
